S Zorb脱硫汽油芳构化反应研究

The Study of S Zorb Desulfurized Gasoline Aromatization Reaction

采用经S Zorb技术处理后的脱硫汽油(简称S Zorb脱硫汽油)作为试验原料,以FDO-2催化剂在微型固定床反应器上进行评价试验;探索了反应温度和压力两个主要操作参数的影响。试验结果表明S Zorb脱硫汽油在体积空速2.0 h-1、氢油体积比500∶1条件下的最佳芳构化反应温度和压力分别是380℃和2.0 MPa。建立反应网络考察了S Zorb脱硫汽油烃类组分的反应历程,探讨了芳构化机理和转化途径。

Using desulfurized gasoline after processing by S Zorb technology（ hereinafter referred to as S Zorb desulfurized gasoline） as test materials,with FDO—2 catalyst evaluated on miniature fixed bed reactor,and explored the reaction temperature and pressure were two main operation parameters. The experimental results showed that S Zorb desulfurized gasoline under the conditions of 2. 0 h- 1volumetric space velocity and hydrogen to oil ratio500： 1,the best aromatization reaction temperature and pressure was 380 ℃ and 2. 0 MPa respectively. Establishing response network to investigate the reaction mechanism of hydrocarbon components of S Zorb desulfurized gasoline,the aromatization mechanism and transformation approach was discussed.
